To achieve the highest protection from an impressed current system we need an anode with a very low consumption rate and a high current capacity. SYNCOR mixed metal oxide (MMO) anodes can reach the above mentioned characteristics.
SYNCOR Mixed Metal Oxide tubular anodes are comprised of a titanium tube, coated by a mixed metal oxide coating of iridium (IrO2) and Tantalum (Ta2O5).
The MMO coating has the following advantageous properties:
- Excellent conductivity
- Resistance to acidic environments
- Chemical stability
- Relatively low consumption rates
- Suitable for use in both chlorine and oxygen evolving electrolytes
- Life expectancy of over 50 years
- Simple and easy to install.
In soil and fresh water applications, the anodes have a recommended current density of approximately 100 amp/m2, and can be operated over 600 amp/m2 in seawater environments. The anode consumption in such high discharge levels is less than 1.0 mg/amp-yr.
